` 10 all whom t 77mg/ concern.'

Be it known that I, XVILLIAMAM- CAvA- NAUGH, a citizen ot the United,States. and a resident of the borough ot' Richmond, .Richmond County,State of N ew York, have in` vented certain new and useful improvelments in Chair Seats, ing .is a specification. Kp v My invention'relates to an iniprovement in seats for chairs, and particularly toleather seats, one of the `objects oli the invention being the provisiono'li' a chair seat in which ilexing' and bending of the leather in themanufacture and application ot the seat have been eliminated.

A further object of the invention is the provision of aunitary leatherchair seat structure which is adapted to be applied to a chair with easeand facility.

A still further object of `my invention is the provision of a chair seatof leather in which a nailing or securing strip is provided ot' whichthe follow'- which is adapted to be secured directly tok the chair, thisstrip being,` independently attached as by sewing for example to themain port-ion or body ot the chair seat, means also being providedwhereby the tacks or other devices employed tor holding the seat inplace are concealed. A

A further object of the invention is the provision ot reinforcingmaterial adapted to he attached to the leather of the seat and to takesome of vthe strain when the seat is iu use.

I am aware that chair seats have heretotore been constructed oi leatherbut the usual practice .is t-o apply a comparatively thin piece ofleather to a wooden frame, the leather being ot' the trame and securedto the frame in any convenient manner.v Such. an arrangement, however,is not satistactoryfor several reasons. in Vthe lirst place turning` theleather down around the edges of the frame causes the leather to verysoon wear through or to craolr,.wl'lile in the second place the leather,in order that it may be folded or turned down around the edges ol.E theframe, must be so thin that it soon wea-rs out.

In my arrangement, a very heavy leather may be employed, sole leatherbeing pre` 4:terred and no turning of the leather down around the edgeof a frame 1s,necessary at all. ln factin my improved `structure theseat 1s a unitary affair and no extra frames or other appurtenances arenecessary at all.

turned down around the edgesV Inthe accompanyingdrawings-f Figure l4illustrates my `improved vchair seat applied 'to a chair, part of theseat being broken away to illustrate itsy construcf tion; ,l

2 'is a bottom ofFig. l; and A i Figs. 3 and 4 are similar viewsotinodilied constructions.

- yReferring to Fig y `l and 2, l designates a chair to which my-improved chair seat may be applied." The chair is provided with theusual seat opening` 2 cut away as indicated to provide a ledge 3 onwhich the chair seat is to rest and by which it is to be supported.

' The chair seat comprises a piece of leather,preferably a. good gradeof sole leather,v designated 4L cut to conform in shape to the opening'2 but small enough so that when in position an annular space designated5 will beleft all around the seat or body of the seat and the chair.

Sewn or otherwise attached to the under side of the body portion 4f is acomparatively narrow strip 6, wide enough to not only rest upon theledge 8, but projects some dista-nce beyond vthe edge of the ledge so asto extend some distance beyond the edge ot the body portion of the seat.This strip may be made in sections it' desired and provides -a flangeall around the edge of the body 4. Interposed between the b ody portionet and thesecuring strip or strips 6 is a reinforcing strip or layer 7ot canvas, wire mesh or other suitable material thisreintorcingmaterialfbeing preferably vcemented to the body portion 4; throughoutits entire surface.

The seat is secured `in position by nailing, for example, through thesecuring strip or strips 6 after which a sectional :filler strip `iscemented or otherwise secured in the spaces 5 between the edges ol the Ybody portion 4 and the frame ot' the chair,

this strip lying Hush with the uppersurtace of thel body il.

It will be seen that this construction pro` vides a very neat andcompact structure with the .means for securing the seat in placeentirely hidden, the usualbending ot the leather about a frame,v in tactthe usual frame, being dispensed with entirely.

My improved structure also provides a comfortable all leather seatwhich-will last almostl indefinitely owing to the fact that the same canbe 4constructed of heavy sole leather it desired, Athe reinforcingmaterial.

plan view et the scat between the top ylos or strip 7 preventingpermanent sag or depression of the body portion 4 so that the neatkappearance of the 'seat is indefinitely preserved.

In the modified form of construction illus` trated in Fig. 3 I haveprovided a chair seat similar to that already described, the canvas orfabric reinforcing strip 7 of Fig. 1 having been, replaced by interlacedthin metal strips 9, and narrow strips 9 of fabric or webbing While inFig. 4 I have used a Woven cane reinforcing structure designatedlO.

Having particularly described my inven,`

Vtion in what I claim and desire tosecureby Letters Patent is:

'1. A chair seat comprising a flat leather body portion, al flat leathersecuring strip secured to the under side of the body por- Z tion andextending beyond the edges thereof U '2. A chair seat comprising aleather body portion, a securing strip secured to the unvder Side of thebody portion and extending beyondthe edge thereof to provide an annula'rflange extending around the edge of the body portion, reinforcingmaterial interposed between the securing strip and` the body portion ofthe seatand secured to both of them, and a concealing strip overlyingsaid flange and lying Hush with the top surface of the body portion.
